VISE.

Specification of Letters Patent.

Application filed April 17 1908.

Patented April 6, 1909.

Serial No. 427,749.

To all whom it may concern:

Be it known that 1, JAMES citizen of the United States, residing in Medford, county of Middlesex, and State of Massachusetts, have invented an Improvement in Vises, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to a portable vise especially designed and adapted among other uses to be employed by plumbers for holding brass, nickel or like pipe without injuring the same.

Provision is made for firmly securing or setting up the vise in any desired position, either horizontally or vertically, as will be described.

The portable vise is further provided with preferably wooden or other non-metallic jaws having recesses or cavities of different sizes for the reception of pipes of different diameters, and provision is made for apply- JOHNSTON, a

ing pressure substantially over or in line one of the cavities, so that each be firmly held between the jaws with a maximum force or pressure.

These and other features of this invention will be pointed out in the claims at the end of this specification.

Figure 1 is an elevation of a portable vise embodying this invention, showing the same as applied to a vertical post or support. Fig. 2, a like elevation of the vise showing the same in its open position. Fig. 3, a plan with the of the vise in a horizontal position,

base plate at right angles to the vise proper. Fig. l, a section on the line l-l, Fig. 1. Fig. 5, a sectional detail to be referred to, and Fig. 6, a sectional detail on the line (3-6, Fig. 3.

Referring to the drawings, a, 6, represent two jaws, preferably of wood or other nonmetallic material, when the Vise is to be used for firmly holding brass, nickel or like pipe which it is desired not to scratch or otherwise injure, but which jaws may be of iron or steel when the vise is to be used with iron pipe.

The jaws a, 7) may be designated the stationary and movable jaws, and are provided on their contiguous faces with a plurality of semi-circular grooves or recesses (Z of different radii, so as to enable the vise to be with any pipe may used with pipes of different sizes or diameters. In the present instance, the jaws a b are shown as provided with five such grooves.

The jaws a, Z), are mounted in jaw carriers g, which are pivotally connected at one end as at h, and are adapted to be locked in their closed position by a locking device as will be described, which is located at the opposite end of the same.

The jaw carrier f may be designated the stationary jaw carrier, and the jaw carrier 9 the movable jaw carrier. The stationary jaw carrier f as shown is recessed for the reception of the stationary jaw a, which rests upon shoulders i (see Fig. l), and may be secured in fixed relation to the said jaw carrier by screws in. The jaw carrier 9 is made hollow for the reception of the jaw b, which is adapted to bear against shoulders we (see Fig. 4), when the vise is in its open position or condition, by means of springs n, which encircle screws extended through the jaw 71 at its opposite ends and engaged with threaded sockets or holes in lugs or projections 22 on the jaw carrier g. The springs n serve to move the jaw I) into the hollow carrier 9 and against the stops or the pressure upon the jaw b is removed. Provision is made for applying pressure over or in line with the pipe inserted between the jaws of the vise. For this purpose, I employ a presser comprising as shown a screw (see Fig. 4t), having a preferably detachable head 12, which may be circular in form and of a size or diameter equal. to or greater than the diameter of the recess (Z for the largest size of pipe, and provision is made for moving the presser longitudinally of the jaw carrier g, so that the same may be brought. into line with any one of the recesses in the jaw 7), and provision is also made for locking or securing said presser in its adjusted position until positively moved by the operator. To this end a movable support is provided for the presser, which has a sliding engagement with the jaw carrier 9, and a locking device movable with the said carrier cooperates with the same to firmly hold the presser support against movement on said carrier. In the present instance the movable support for the presser is shown as made in two parts or sections which may be designated the lower and upper parts or sections. The lower shoulders m, when part or section consists of a substantially flat plate 1 (see Fig. 4) having a central opening 15, ribs 16 on opposite sides of said opening and side flanges 17, which fit over guiding ribs 18 on opposite sides of the longitudinally slot-ted jaw carrier 9.

The upper part or section consists of a plate 19 having one set of side flanges 20, which are secured as by pins 21 to the ribs 16, and another set of side flanges 22, which fit over and are guided on side bars 23 of a slotted frame, which is located in the same plane as the jaw carrier 9 and is connected therewith by tie bars or arms 24.

The section 19 of the movable support or sliding carrier for the presser is provided with a tubular extension 25, arovided with internal screw-threads which are engaged by the threaded shank or rod 10 of the presser, and which is provided on its exterior with screw-threads, which are engaged by nuts 26, 27 separated from each other and to which are secured the opposite ends of a helical spring 28 (see Figs. 4 and 5) which serves to rotate the nut 27 in such direction that it will be turned on the extension 25 into engagement with the side bars 23 of the slotted frame attached to the carrier 9.

The nut 27 is provided with a tubular extension or sleeve 29, which serves to conceal and protect the spring 28. The spring-actuated nut 27 constitutes an automatic lock or holding device for the movable or sliding support for the presser, and serves to hold the presser in the position into which it is moved by the operator. To release the presser, the nut. 27 is turned by the operator so as to wind up the spring 28 (see Fig. 5), and thereby disengage the nut from. the side bars 23, and when the presser is thus unlocked, it may be moved longitudinally of the vise to position the presser with relation to the particular recess in the jaw b with which the pipe to be worked cooperates.

The presser head 12 may be detachably secured to the screw or threaded rod 10, which may be effected by an internally threaded sleeve or nut 30, which is fitted over the screw rod 10, is retained thereon by a collar 31 fastened on the rod by the pin 32, and engages a threaded projection 33 on the presser head 12.

The projection 33 may be provided with a socket for the reception of the end of the screw rod 10, which end may be round.

Provision is made for locking the jaw carriers f, 9, together, and for this purpose, the movable jaw carrier 9 is provided with sliding'bolts 35 (see Fig. 6), which extend transversely of said carrier and are adapted to be forced into holes 37 in lugs or ears 38 on the sides of the stationary jaw carrier f, by means of a spring 39 interposed between said bolts. In the present instance, a single into sockets in the inner end portions of the bolts. The boltsu35 may be provided with lugs 40 extended up through slots in the end ofthe movable jaw carrier 9, so as to render them conveniently accessible.

Provision is made for firmly securing the vise to a wooden or other non-metallic support 41, such as a post or wall of the cellar or a room of the house. For this purpose, I employ a base plate 42, which is pivotally mounted on a hub or hollow boss 43 extended from the underside of the stationary jaw carrier f, and provided with screwthreads which are engaged by a nut 44 located in a recess 45 in the underside of the base plate, which nut serves to retain the base plate on said boss, while leaving the base plate'free to be rotated on the said boss or the vise to be turned with relation to the base plate.

The base plate may and preferably will be provided with a square or angular socket 46 in line withthe hollow boss for the reception of the head 47 of a large screw 48, which is extended through the hollow boss and is adapted to be screwed into the post or wall 41 by using the vise proper as an instrument for turning the said screw. The head 47 of the sore is confined in its socket 46 in the carrier f by the stationary jaw a.

In applying the vise to the post, the operator grasps the vise preferably with the jaw carrier locked together, and jams orforces the end of the screw 48 into the post until the thread catches into the same. He then turns the vise so as to force the screw farther into the post until the base plate 42 has been brought into sufficient proximity to the post to cause spurs or projections 49 on the base plate to enter the wood, after which the vise is turned until the base plate is brought into contact with the post or substantially so, and when this is done, the vise is turned into line with the base plate and locked thereto, by means of dogs 50 pivoted to the ends of the stationary jaw carrier f and engaging cam-shaped or inclined under surfaces 51 of slotted lugs or ears 52 on the ends of the base plate. The spurs 49 serve to resist movement of the base plate and the vise locked thereto and also serve to relieve the screw 48 from strain. Provision is made for retaining the locking dogs stationary in their unlocked position, that is, extended. in line with the jaw carrier as represented in Fig. 3, so that thevise may be turned freely without'the locking dogs striking the base plate 42. To this end, I have provided fiat springs which are secured to the ends of the jaw carrier f and have their free ends engaging the rear ends of the locking dogs, which ends may be provided with flattened portions'56 (see Fig. 1), which are engaged. by the springs 55 and serve to hold the lockspring is used, which has its end extended i ing dogs stationary in their extended position in line with the stationary jaw carrier, until the locking dogs are turnec by the operator to engage them with the lugs 52 on the plate.

From the above description, it will be seen that the vise is portable and can be up in the collar or other place by the plumber or other operator in 2 short time, which avoids the necessity oi the plumber carting the heavy ouch and vise now coi'x'nnonly employed by him, and which is mpable of being used for all kinds of pipes, and especially brass or nickel, witluiut scratching or otherwise injuring" the same. l urthermore the desired pressure is provided for gripping or holding each of a plurality of pipes or dilloreut sizes, for after the presser is adjusted on the movable jaw arrier in line with the pipe to be cut, threaded or otherwise worked upon, the screw 10 may be turned by the operator by means of the handle or bar 53, so as to force the movable jaw 1), against the pipe 0 until the latter is tlrnily p'rip ied or clamped between the jaws a, l).

I have herein described the invention as embodied in a portable vise provided with jaws having recesses or grooves for the reception of pipes, but it is evident that the vise may be us d to advantage tor other classes of work, for which it would only be necessary to replace the grooved jaws, with jaws having straight or tlat surfaces.

l have herein shown the presser as operated by rotating the screw rod 10, but 1 do not desire to limit my invention to this particular method of operating the presser.
